Further, whether or not the accelerator operation amount and the brake operation amount are in a range where the fuel efficiency is good can be distinguished by boundary lines in different directions across the reference position. For this reason, when [accelerator pedal / brake pedal] is switched, the displayed figure changes greatly, and the boundary line that the driver should pay attention to changes in a different direction across the reference position.

Description
図1は本発明の表示装置適用する車両の一例を示す略構成図である。
エンジン1は、ガソリンエンジンやディーゼルエンジンなど、燃料を燃焼させて動力を出力する公知の動力装置であって、吸気通路11に設けられたスロットルバルブ13のスロットル開度、燃料噴射装置15による燃料噴射量、及び、点火装置16の点火時期などの運転状態を制御できるように構成されている。エンジン1には、出力軸であるクランクシャフト10の回転角(クランク角)を検出するクランクポジションセンサ101が配置されている。このクランクポジションセンサ101の出力信号からエンジン回転数を算出することができる。また、エンジン1には排気通路12が接続されており、燃焼後の排気ガスは排気通路12を経て図示しない酸化触媒等の排気浄化装置19による浄化が行われた後に大気中に放出される。
トルクコンバータ(T/C)2は、入力軸側のポンプインペラ、出力軸側のタービンランナ、トルク増幅機能を発現するステータ、及び、ロックアップクラッチなどを備え、ポンプインペラとタービンランナとの間で流体(ATF)を介して動力伝達を行う公知の流体継手である。このトルクコンバータ2のポンプインペラはエンジン1のクランクシャフト10に連結されており、タービンランナは自動変速機3の入力軸に連結されている。
自動変速機3としては、例えば、プライマリプーリ、セカンダリプーリ、及び、これらプライマリプーリとセカンダリプーリとの間に巻き掛けられたベルトなどを備え、変速比を無段階に調整するベルト式の無段変速機(CVT:Continuously Variable Transmission)が用いられている。なお、自動変速機(無段変速機)3と上記トルクコンバータ2との間の動力伝達経路には前後進切替機構(図示せず)が設けられている。
また、この例の車両100には、図3に示すように、スタータモータ17、オルタネータ18、バッテリ20、及び、空調装置(空気調和装置)50などが搭載されている。
(空調装置)
この例の車両100には、車室内の暖房や冷房を行うための空調装置50(図3参照)が搭載されている。空調装置50は、車両100の車室内に調和空気を導くための空気通路を形成する空調ダクト(図示せず)と、この空調ダクト内で空気流を発生させるブロワ52、主として車室内の冷房時に上記空調ダクト内を流通する空気を冷却するための冷凍サイクル(コンプレッサ51、コンデンサ、膨張弁、エバポレータ等)、及び、主として車室内の暖房時に空調ダクト内を流通する空気を加熱するためのヒータコア(図示せず)などを備えている。なお、空調装置50は、車室内の温度を設定する温度設定スイッチ、及び、ブロワ風量を設定するブロワスイッチなどを備えている。
この例の車両100には、図3に示すようなシフト操作装置8が設けられている。このシフト操作装置8は運転席の近傍に配置されている。シフト操作装置8には変位操作可能なシフトレバー81が設けられている。
この例の車両100には、運転者による車両の運転操作状態(運転操作量)や電力・空調の使用状況などを表示する運転状態表示部(エコドライブインジケータ)31が装備されている。以下、この運転状態表示部31について説明する。
ECU200は、CPU(Central Processing Unit)、ROM(Read Only Memory)、RAM(Random Access Memory)及びバックアップRAMなどを備えている。
この例の車両100はアイドリングストップ車両であって、ECU200は、アイドリングストップ条件(エンジン自動停止条件)が成立した場合にエンジン1を自動的に停止し、アイドリングストップ解除条件(エンジン自動始動条件)が成立した場合にエンジン1を自動的に始動する、いわゆるアイドリングストップ制御(エコラン制御)を実行することが可能である。
次に、ECU200が実行する運転状態表示部31の表示制御について説明する。
車両100が走行中の場合には、運転状態表示部31の表示は図4(A)に示す形態の表示(アクセル操作量を示す表示)となる。
このようにして現状のアクセル操作量を示すアクセル操作量表示バー31eの表示を制御することにより、そのアクセル操作量表示バー31eの表示長(伸長量)は、アクセル操作量に応じた燃費に合わせて変化するようになる。つまり、アクセル操作量表示バー31eの表示長は、燃費が良好なアクセル操作量であればあるほど短くなる(Xb方向への伸長量が縮小する)。一方、燃費が悪くなる側のアクセル操作量であればあるほどアクセル操作量表示バー31eの表示長が長くなる(Xb方向への伸長量が増加する)。なお、走行中にブレーキペダル7が操作されない状態(ブレーキ操作量=0)でアクセルオフ(アクセル操作量=0)である場合は、アクセル操作量表示バー31eの伸長量が0(基準位置31a)となる。
車両100が減速中(ブレーキ操作による減速中)の場合には、運転状態表示部31の表示は図4(B)に示す形態の表示(ブレーキ操作量を示す表示)となる。
このようにして現状のブレーキ操作量を示すブレーキ操作量表示バー31eの表示を制御することにより、そのブレーキ操作量表示バー31eの表示長(伸長量)は、ブレーキ操作量に応じた燃費に合わせて変化するようになる。つまり、ブレーキ操作量表示バー31eの表示長は、燃費が良好なブレーキ操作量であればあるほど短くなる(Xb方向への伸長量が縮小する)。一方、燃費が悪くなる側のブレーキ操作量であればあるほどブレーキ操作量表示バー31eの表示長が長くなる(Xb方向への伸長量が増加する)。
次に、車両100が停車中であってアイドリングストップ前の状態での表示は、図4(C)に示す形態の表示(ブレーキ操作量を示す表示)となる。
このようにして現状のブレーキ操作量を示すブレーキ操作量表示バー31eの表示を制御することにより、そのブレーキ操作量表示バー31eの表示長(伸長量)は、ブレーキ操作量に応じて変化するようになる。つまり、ブレーキ操作量表示バー31eの表示長は、ブレーキ操作量がアイドリングストップの判定閾値THbrk1に近くなればなるほど長くなる(Xb方向への伸長量が増加する)。
アイドリングストップ中において、現状の電力使用量が後述する基準値Thpow1未満であり、かつ、現状の空調使用量が後述する基準値Thpow2未満であるという条件が成立している場合には、図8に示す形態の表示(電力使用状況の表示)が表示される。
このようにして現状の電力使用量を示す電力使用状況表示バー31eの表示を制御することにより、その電力使用状況表示バー31eの表示長(伸長量)は、電力使用量に応じて変化するようになる。つまり、電力使用状況表示バー31eの表示長は、現状の電力使用量が電力使用量の基準値Thpow1に近づくほど長くなる(Xb方向への伸長量が増加する)。
電力使用量の基準値Thpow1については、例えば、車両100の位置に関する位置情報(騒音等の情報)、日時情報(月日、時刻などの情報)、天候情報(天気(晴・曇・雨・雪等)、外気温度等の情報)などの外部情報(外部条件)をパラメータとして、運転者を含むユーザによって操作される車載機器、例えば、空調装置50のブロワ52、ヘッドランプ、オーディオ装置、ワイパなどの各車載機器について最適な電力使用状況(電力量)が予め設定されたテーブルを用い、上記外部情報(外部条件)に基づいて上記テーブルを参照して各車載機器ごとの最適電力使用量(外部条件に対応した最適電力使用量)を求め、それらの合計値に、ユーザ操作に関係なく常に駆動される車載機器の電力使用量の合計値を加えたものを電力使用量の基準値Thpow1とする。
アイドリングストップ中において、ユーザ操作によって実際に設定されている各車載機器の使用状況(ブロワ52、ヘッドランプ、オーディオ装置、ワイパなどの各車載機器の実際の電力使用レベル)から、それら車載機器の現状の電力使用量の合計値を求め、その求めた実際の電力使用量の合計値に、ユーザ操作に関係なく常に駆動される車載機器の電力使用量の合計値を加えたものを現状の電力使用量とする。さらに、アイドリングストップ開始時からの経過時間(電力使用量の積算値)に応じて現状の電力使用量を増加していく(電力使用状況表示バー31eを伸長していく)ようにする。
空調使用量の基準値Thpow2については、例えば、上記外部情報(外部条件)をパラメータとして、ブロワ52について5段階の最適電力使用レベル(L0(=0)~L4(最大))が上記外部情報(外部条件)に対応して設定されたテーブルを用い、上記外部情報(外部条件)に基づいて上記テーブルを参照してブロワ52の最適電力使用量を求めたものを空調使用量の基準値Thpow2とする。なお、ブロワ52の最適電力使用量を求めるためのテーブルは、予め実験やシミュレーションによって作成されており、ECU200のROM内に記憶されている。
次に、運転状態表示部31の表示制御の一例について図9及び図10のフローチャートを参照して説明する。図9及び図10の制御ルーチンは、ECU200において所定期間(例えば数msec)ごとに繰り返して実行される。
以上説明したように、本実施形態によれば、運転者は、運転状態表示部31の表示から、現状のアクセル操作量が燃費が良好な領域にあるか否かを視覚的に確認することができる。また、ブレーキ操作量が燃費が良好な領域にあるか否かを視覚的に確認することができる。
以上の[実施形態1]にあっては、アイドリングストップ中であり、現状の電力使用量が基準値Thpow1未満、かつ、現状の空調使用量が基準値Thpow2未満である場合に、運転状態表示部31に電力使用状況を示す表示(図8参照)を表示するようにしているが、これに限られることなく、他の状況を含む複数の表示のうちの1つを選択的に表示するようにしてもよい。その一例を図11(A)~(C)に示す。この図11(A)~(C)の各図の表示について説明する。
このようにして現状の空調使用量を示す空調使用状況表示バー31eの表示を制御することにより、その空調使用状況表示バー31eの表示長(伸長量)は、空調使用量に応じて変化するようになる。つまり、空調使用状況表示バー31eの表示長は、現状の空調使用量が空調使用量の基準値Thpow2に近づくほど長くなる(Xb方向への伸長量が増加する)。
このようにして現状のブレーキ操作量を示すブレーキ操作量表示バー31eの表示を制御することにより、そのブレーキ操作量表示バー31eの表示長(伸長量)は、ブレーキ操作量に応じて変化するようになる。つまり、ブレーキ操作量表示バー31eの表示長は、ブレーキ操作量がアイドリングストップの判定閾値THbrk2に近くなればなるほど長くなる(Xb方向への伸長量が増加する)。このような表示により、運転者は、現状のブレーキ操作量がアイドリングストップ領域31dにあるか否かを視覚的に確認することが可能になる。また、運転者は、エンジン自動始動とするために、ブレーキペダル7の戻し操作を、あとどのくらい行えばよいのかを視覚的に認識することができる。
以上の[実施形態1]、[変形例1]では、運転状態表示部31に境界線31bを表示しているが、これに替えて、例えば図12に示すように、運転状態表示部31に上限値と下限値とを有する範囲31h(領域を視覚的に区別可能とする範囲)を表示するようにしてもよい。
次に、手動クラッチ及び手動変速機を備えたアイドリングストップ車両に搭載される表示装置の例について以下に説明する。
この図13に示すような表示により、運転者は、現状のクラッチ操作量がアイドリングストップの許可領域31dに達しているか否かを視覚的に確認することが可能になる。また、運転者は、アイドリングストップ(エンジン自動停止)とするために、クラッチペダルを、あとどのくらい踏み込めばよいのかを視覚的に認識することができる。
この図14に示すような表示により、運転者は、現状のクラッチ操作量がアイドリングストップ領域31dにあるか否かを視覚的に確認することが可能になる。また、運転者は、エンジン自動始動とするために、クラッチペダルの戻し操作を、あとどのくらい行えばよいのかを視覚的に認識することができる。
なお、今回開示した実施形態は、すべての点で例示であって、限定的な解釈の根拠となるものではない。したがって、本発明の技術的範囲は、上記した実施形態のみによって解釈されるものではなく、特許請求の範囲の記載に基づいて画定される。また、本発明の技術的範囲には、特許請求の範囲と均等の意味及び範囲内でのすべての変更が含まれる。
